World's last male white rhino protected by armed guards in 2017

The last male northern white rhino has died, leaving only two females to save the species from total extinction.
Sudan, the “gentle giant” who lived on the Ol Pejeta Conservancy in Kenya, was put down on Monday after the pain from a degenerative illness became too great. He is survived only by his daughter and granddaughter.
